xargs to concatenate extension onto an argument

Question

I am trying to set up a script to automatically delete a .torrent file based on an output from transmission-remote.

transmission-remote http://localhost/transmission -l | grep 100% | grep Finished | awk '{print $10}' | xargs -I% -r -p -n 1 /bin/rm /mnt/samba/Dropbox/%.torrent

Here is my current output:

/bin/rm /mnt/samba/Dropbox/MyTorrent.torrent ?...y

/bin/rm: cannot remove `/mnt/samba/Dropbox/MyTorrent.torrent': No such file or directory

The name that is outputted is identical to the .torrent name

root@mfalc:/mnt/samba/Dropbox/# ls
MyTorrent.torrent
root@mfalc:/mnt/samba/Dropbox/# 

Here is also what it looks like before the awk

root@mfalc:~# transmission-remote http://localhost/transmission -l | grep 100% | grep Finished | grep Done 
  12   100%  174.4 MiB  Done         0.0     0.0   0.01  Finished     MyTorrent

I have obscured the actual torrent name but, does anyone have any suggestions? Am I concatenating the .torrent extension with xargs correctly?

Answer 1

Well you don't need xargs for that, awk can do it for you (only that part):

awk '{print $10 ".torrent"}'

Even better awk can call rm on it:

awk '{system("rm -i " $10 ".torrent")}'

If you have space(s) in the torrent names:

awk '{system("rm -i " gensub(" ","\\\\ ","g",$10) ".torrent")}'
